Questions about the 3.6.5 TODO thread

Can you describe the * and # system used in the 3.6.5 TODO thread? Maybe # refers to items which have a fix ready? But *?

On a similar note, if 3.6.5 will include untested new features, is there a chance that we can get a 3.6.4a or 3.6.4.1 bugfix release sent to Wordpress in the interim? (also allowing us to wait for feedback on how stable 3.6.5 turns out)
